A simple plugin that allows for the right clicking of any folder or file and allowing it to be opened in a File Browser, Command Prompt, or (for Windows) Cygwin. Currently only Windows is supported, but I'd like to add Mac OSX and Linux support.
To solve my requirement for a lazy, single-request data source, I created the (obviously named) LazyLoadDataSource. It's much like the XHRDataSource, except it expects to retrieve all the data in a single request. Now I can create more efficient auto-completes that can retrieve data on demand while keeping requests to the server at an absolute minimum.
